Interfacing LCD with Atmega32 Microcontroller using Atmel Studio

As we all know LCD (Liquid Crystal Display) is an electronic display which is commonly used nowadays in applications such as calculators, laptops, tablets, mobile phones etc. 16×2 character LCD module is a very basic module which is commonly used by electronic hobbyists and is used in many electronic devices and project. It can display 2 lines of 16 character and each character is displayed using 5×7 or 5×1 ...

Temperature sensor with time and date display on graphical LCD

Some time ago I've build a prototyping board with graphical LCD. It have served for various small projects and prototypes. Had a spare temperature sensor DS18B20 and decided to put simple temperature display project. GLCD board is equipped with Atmega32 microcontroller running at 16MHz. DS18B20 sensor is connected to port D pin 6. LED connected to PD3 is used for indicating EEPROM write activity. Device is ...

Graphical LCD Text Display

The Graphical LCD Text Display is complete!   I've used the same Atmel ATMega8 controller that I used in the Composite Video Display.   The interface is the same as well; an 8 bit parallel port with a strobe input and a busy output.   It can be connected directly to a 65C22 8 bit port or any generic parallel port with ease. The Display is an Optrex DMF50840A which supports 320x240 with a Cold Compact Floure ...

Accelerometer and Relay based Hand Gesture Controlled Wireless Home Automation System with ATmega32 using 433MHz RF

In this project, we will learn How to design an Accelerometer and Relay based Hand Gesture Controlled Wireless Home Automation System with AVR ATmega32 microcontroller using 433MHz RF. Here, we will use different hand gestures as input signal to control the appliances i.e 2 bulbs and 2 fans. Also, we will display the status of the appliances in a 16X2 alphanumeric LCD. In our case, hand gestures mean tilt o ...

Veronica – VRAM

I considered subtitling this article, “adventures in breadboard noise”, since that’s what I spent most of my time dealing with. In any case, let’s recap where we were. Veronica’s video generator was generating a stable VGA signal. In addition, a test pattern was being displayed by altering pixel colors on the fly during the scanning process (so called “racing the beam”). That’s pretty flashy, but ultimately ...
